what speed to expect

Recommended Posts

Hi All 

just wondering what speed I should be expecting for 308 loads in 155,175 and 185 grain bullets, chrono,ed  my loads and am getting 2700 for 155;s ,  high 2500,s for the 175's ,and only 2300 for the 185's . So although accurate loads at 100-300 m I would like to know what speeds would be good for upto 1000m . currently using   N550 but moving to N150 

cheers

RS52 is the powder for 155grain bullets in 308.......46.5 grains gives an accurate 3000fps MV in mine. (30" 11 twist Bartlein)
